Rare also used to be good before Microsoft bought them. 

Mercury Steam made crappy Castlevania games under Konami, but under the guidance of Nintendo they made a good Metroid game. 

Microsoft mismanages their studios, that much is clear. They're no Nintendo or Sony when it comes to managing their development studios.

Hope it's true.

Because they ruin and close many of the studios they purchase.

How so, can you provide links to how they do this to there studios? Or are you referring to the struggling studios under them that in some cases require them to close the doors or reshuffle them? Much like every other company like Sony and Nintendo do all the time aswell.

I just want to point out that I don't think this is the case with Quantum Break.

Sami Järvi (Sam Lake) explained in an interview with Finnish gaming magazine that before Xbox One was even launched, it was Remedy's idea to combine a video game and a tv-show. They brought this idea to Microsoft and because Microsoft had plans with television stuff for Xbox One, they encouraged Remedy to take this tv-show idea even further. Järvi says everyone at Remedy agreed that they want to be even more ambitious and make the game bigger. 

Here's a link to one interview, it's in Finnish though https://www.savonsanomat.fi/kulttuuri/Quantum-Break-on-Remedyn-j%C3%A4ttisatsaus-Rahallisesti-voidaan-puhua-isosta-Hollywood-tuotannosta/752224

edit. here's an interview in English https://venturebeat.com/2016/04/11/remedys-sam-lake-stepped-up-the-creativity-and-ambition-with-microsofts-quantum-break/

Microsoft made it possible for Remedy to push their vision further. Must have been great for Remedy.

"The actors, having known talent on this level—that was in the talks, very early on. It came from this idea of creating a big Hollywood blockbuster type of experience. But it was in large part thanks to Microsoft being willing to fund the idea and give us the support to pull it off".

How many of Sony's major studios where acquisitions done in the past?

I like how hard you pretend it's not a thing that happens.

Currently Active:

Media Molecule was acquired by Sony in 2010.

Sucker Punch was acquired by Sony in 2011. 

Guerrilla Games was acquired by Sony in 2005. 

Naughty Dog was acquired by Sony in 2001.

Bend Studio was acquired by Sony in 2000.

Defunct: 

Zipper Interactive got acquired by Sony in 2006 then got closed by them in 2012. 

Evolution Studios were acquired by Sony in 2007 then got closed by them in 2016.

bigbig Studios was acquired by Sony in 2007 then got closed by them in 2012.

That's at least 8 acquisitions, i'm not even sure I found them all since this is just from a quick search through that wikipedia page. So according to Kerotan Sony must be lazy as well. 

Not sure all of them necessarily count as 'major' studios but they were acquisitions none the less. 

Yeah, I agree. But the problem is somewhere else. Obsidian offers stuff in a niche, that is not big but has very engaged fans. Before Pillars there was basically nothing in that niche for years. A studio so significant going to a first-party is a problem, as the content gets locked into specific platforms. I wouldn't mind if Obsidian goes to Ubisoft, Sega or THQ Nordic.

I hope it's true. good on MS.
